Describe the difference between competitive and noncompetitive inhibitors.

• noncompetitive binds to active site blocking the substrate and competitive binds to a different place on the enzyme that causes the active site to change shape

• competitive binds to active site blocking the substrate and noncompetitive binds to a different place on the enzyme that causes the active site to change shape

• competitive is irreversible and noncompetitive is reversible binding

• noncompetitive is irreversible and competitive is reversible binding

What are the products of the light reactions of photosynthesis?

• ATP & NADH

• CO₂ & H₂O

• NADPH, ATP and O₂

• Organic Compounds & O₂

What is the function of the electron transport chain between Photosystem II and Photosystem I?

• establish electrochemical gradient of protons

• to funnel electrons into photosystem I for the Calvin cycle

• transport electrons to oxygen to make water

• to synthesize ATP using ATP synthase

Where does the Calvin cycle take place?

• thylakoid membrane

• cristae

• stroma

• matrix

Which of the following are electron carriers for the electron transport chain in cellular respiration?

• NADPH

• FADH₂

• NADH

• NADH & FADH₂
